ABSTRACT

Linear motor was invented at the beginning of the electric machine era. Iiowevcr they are widel)'

applied in the last few years. The analization, calculation forces acting on the machine are necessary jot

using this type of machine with high effect. In this paper, the forces of permanent magnet linear motor an

analyzed and calculated. Ther results were verified by simulation software and practical measurement
